I have a question on building molds. My experience with mold makeing for fiberglass is that the mold (if made of fiberglass) needs to be at least twice as thick as the piece you are going to make. So, the heat from the part wont warp the mold.
1. What type of material is being used to pull molds? 2. If making of glass how thick and are you using a spray on release agent? Molds I have made before have been from. Glass, Sheetrock mud, plaster of paris, paper machae, clay, even concrete. I just want to know what KR people are doing. Steven Phillabaum Auburn, Alabama
